MACHINE FOR MAKING DRAIN-TILE.

QPECIPICATION forming part of Letters Patent No. 326,018, datedSeptember 8,1885.

Application tiled March 9, 1885. (No model.)

.To all whom it may concern:

Be it k nown that we, ROBERT J. CARSON and WILLIS D. SHERMAN, citizensof the United States, residing at Dixon, in the county of Lee and Stateof Illinois, have invented certain new and useful Improvements in-Machines for Making Drain-Tile,- and we do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

Our invention pertains to machines for making drain-tile, and refersmore especially to certain novel mechanism for packing the material insuch molds and at the same time boring out the center thereof.

The class of tile to which our invention is at present applied is thatconstructed of a composition which 'hardens sufficiently from drying,and the usual operation of burning is therefore unnecessary.

In the drawings, Figure l is a front elevation of a machine embodyingour invention. Fig. 2 is a side elevation of the same. Fig. 3 is asection in line as a: of Fig. 2. Fig. 4 is a detail View of the gear forraising or lowering the packer and hopper.

A is the frame of the machine which supports the mechanism hereinafterdescribed.

B is a table, suitably attached to the frame A.

O O are the molds, which are cylinders at- 5 tached in vertical positionto the upper side of the table 13, and into which cylinders the materialfor the tile is conveyed by the spout O.

D D are hoppers to receive the material and conduct it into the molds O.The hoppers D are 0 supported by chains D from a cross-tree, D attachedto the vertical shafts of the packers E, and have their lower convergedendsinserted in the upper ends of the molds G.

E E are packers, having their lower ends 4 furnished with the obliquewings E, so placed that the lateral rotation of the packers E will causesuch wings to pack the material in the molds O, and at the same timeride over the material as packed, and will thereby be gradually ed inthe molds O.

raised to the top of such molds. The packers E E are further furnishedwith transverse stir rers E, at different points on their shafts, thefunction of which is to distribute the ma erial equally over theinternal area of the molds.

The packers E are attached to the frame A, 5

on a horizontal shaft, H ,(ti1e latter being 6 actuated in any suitableway,) and the rotation of one shaft E through the medium of thesprocketchains G is communicated to the other packer-shaft,

A shaft, I, is journaled on the frame A transversely to the shafts E andbetween such shafts provided with a pinion, I, which engages a verticalgear-rack, 1 depending from the cross-tree D. In the process of packingthe molds G the rack I is parried to the top of the frame A, and whenit'is required to lower the packer, by means of the crank 1 the pinion lisrotated, and the latter, by engagingwith the gear-rack I forces thepack ers to the bottom of the molds O. The same means can be employed toraise the packer, should it become necessary to do so.

K is a horizontal shaft, driven by means of the belt K from the shaft.11. A bevel-pin-' ion, K", on the inner end of the shaft K, engages androtates a bevel gear-wheel, L, feathered on the auger M.

M M are angers, designed to bore out the center of the tile as thelatter are being mold- The angers M are hollow 9o cylinders, having acutting-edge at their upper extremity. They are rotated by means of asprocket-wheel, N, integral with the gearwheel L, which wheel N isconnected by the sprocketchain N to a corresponding sprocket- 9 5 wheel,N, feathered on the other auger M. The gear-wheel L and sprocket-wheelsN are suitably supported by the frame A.

The angers M are seated pivotally at their lower ends in the horizontalplate 0, and have collars M above and below such plate.

A lever, P, is suitably fulcrumed near its center on the arm A projectedfrom the frame A, and at its inner end is pivotally attached to thecenter of the plate 0, and by means of thelever P the angers M areforced upward into the molds O as the process of boring is beingaccomplished. The angers M pass upward through corresponding openings inthe plate B.

The material removed in the process of boring' drops into the hopper Sand is'earried from thence by means of the elevator T and dischargedinto the feed-hopper. (Not shown.)

What we claim as our invention, and desire to secure by Letters Patentof the United States, is-

1. In a tile-machine, the combination of the molds O, packers E, andangers M, substantiall y as shown, and for the purpose described.

2. In a tile-machine, the construction and relation, substantially asshown, of the molds O, packers E, and angers M, for the purpose Ispecified.

3. In a tile-machine, the combination of the molds O, packers E, andangers M, plate 0, and lever I, substantially as shown, and for thepurpose described.

4. The combination of the molds G, packers E, sprocket-wheels G, chainG, bevel-gears H and H, and shaft H substantially as shown, and for thepurpose specified.

5. The combination of the angers M, molds G, sprocket-wheels N, chain N,gear-wheels K and L, and shaft K, substantially as shown, and for thepurpose described.

6. The combination of the packer E, shaft I, pinion 1, frame A, andgear-rack 1 substantially as shown, and for the purpose mentioned.

7 The combination of thehoppers D, chains D, cross-tree D and packers E,substantially as shown, and for the purpose described.

In testimony whereof we affix our signatures in presence of twowitnesses.
